    _warning**: NRF (Non Redundant Fraction) is equal to the result of the division\
    \ of the number of reads after duplicates removal by the total number of reads.\
    \ An NRF value in the range 0 - 0.5 is poor complexity, 0.5 - 0.8 is moderate\
    \ complexity, and > 0.8 high complexity. NRF value > 0.8 is recommended, but >\
    \ 0.5 is acceptable. ENCODE processed alignments file {ENCFF785SBQ|/files/ENCFF785SBQ/}\

    \ 1, M1/M\\_distinct) is the ratio of the number of genomic locations where exactly\
    \ one read maps uniquely (M1) to the number of genomic locations where some reads\
    \ map (M\\_distinct). A PBC1 value in the range 0 - 0.5 is severe bottlenecking,\
    \ 0.5 - 0.8 is moderate bottlenecking, 0.8 - 0.9 is mild bottlenecking, and >\
    \ 0.9 is no bottlenecking. PBC1 value > 0.9 is recommended, but > 0.8 is acceptable.\

    \ is the ratio of the number of genomic locations where exactly one read maps\
    \ uniquely (M1) to the number of genomic locations where two reads map uniquely\
    \ (M2). A PBC2 value in the range 0 - 1 is severe bottlenecking, 1 - 3 is moderate\
